First Personal Python Project – Learning in Public So I finally built my first “real” Python project — a Budget Tracker CLI — as part of my journey from Data Analysis → Machine Learning Engineering. What it does (in simple terms): - Add, edit, and delete expenses from the terminal - Update a budget and instantly see what’s left - Save everything to JSON and auto-load when the app restarts - Generate a receipt-style text report - Handles basic file errors (so it doesn’t crash if something goes wrong) What I actually learned from this: - How to structure code properly using OOP - Working with file paths using pathlib (no more messy path strings 😅) - Saving and loading data with JSON - Thinking about how real apps start, run, and shut down cleanly Why this matters to me: Before jumping into ML models, I’m focusing on getting really solid with Python fundamentals — especially how applications manage data, persistence, and logic. Feels like building the “engine room” before flying the ML rocket 🚀 🔗 GitHub Repo: https://lnkd.in/eS3hjcEb 🎥 Demo attached below #Python #DataAnalytics #MachineLearningJourney #LearningInPublic #ML #DataEngineering

Most people still think Python is “just a programming language.” That’s a narrow view — and honestly, it’s outdated. Python is an ecosystem. Pair it with the right libraries and it becomes a tool for almost anything: • Pandas → Data manipulation • TensorFlow → Deep learning • Matplotlib / Seaborn → Data visualization • BeautifulSoup / Selenium → Web scraping & automation • FastAPI / Flask / Django → APIs & web platforms • SQLAlchemy → Database access • OpenCV → Computer vision & beyond The real leverage isn’t in learning Python syntax. It’s in understanding which stack solves which problem — and how to combine them efficiently. If you’re learning Python, stop collecting tutorials. Start building use-case stacks. That’s where the actual career advantage is. #Python #DataScience #MachineLearning #WebDevelopment #Automation #AI #Programming #TechCareers

#Python has become the lingua franca of #optimization. 6 years ago, if you were building serious optimization models, C++ was the default. Today, Python dominates the field. Why the shift? - Ease of Use: Clean syntax that shortens development cycles and lowers barriers to entry. - Rich Ecosystem: Seamless integration with data (Pandas), visualization (Plotly), and ML (Scikit-learn) for end-to-end decision intelligence pipelines. - Community: Python is what students are learning. It's democratizing optimization. But there are trade-offs to watch: ⚠️ Performance: Python is slower than C++. For large-scale applications, this matters. ⚠️ Efficiency: Know your bottlenecks. Most practitioners focus on solve time when model build time is the real culprit. The solution? Write efficient Python code: ✅ Use NumPy arrays and vectorization ✅ Leverage list comprehension instead of explicit loops ✅ Avoid nested for loops that kill performance ✅ Use the right data structures FICO Xpress's Python API makes this easy with native support for NumPy arrays, efficient problem building with addVariables(), and seamless integration with the full optimization suite. Link in the comments for some Xpress Numpy examples. The move to Python is democratizing optimization. More people than ever are building powerful decision models. Are you leveraging Python for your optimization projects? #DecisionIntelligence #DataScience #Xpress

If Python was a person, I feel like it would be that calm friend that can literally do almost anything. 😁 You need it for web or app development? “I am here.” You want to automate something boring? “No problem.” For Data analysis? “Let’s do it.” Machine Learning? “Why not?” What I love about Python is not just that it is easy to read. It is the fact that it grows with you. You can start with simple scripts. Move into development, explore automation, and even AI. The more I learn, the more I see that Python is not just a language, it is a tool that adapts to wherever you are going. And that is why I am sticking with it. What programming language feels like home to you? #Python #BackendDevelopment #Automation #AI

I wasted 6 months "learning Python." Watched 50 tutorials. Read 10 articles. Couldn't build ONE real project. The problem? No roadmap. Here's the path that finally worked: 𝗠𝗢𝗡𝗧𝗛 𝟭: 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻 → Variables, data types, operators → If-else, loops, functions → Basic input/output Build: Calculator, number guessing game 𝗠𝗢𝗡𝗧𝗛 𝟮: 𝗗𝗮𝘁𝗮 𝗦𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀 → Lists, dictionaries, tuples, sets → List comprehensions → File handling (read/write) Build: Todo list app, CSV data parser 𝗠𝗢𝗡𝗧𝗛 𝟯: 𝗢𝗢𝗣 𝗕𝗮𝘀𝗶𝗰𝘀 → Classes and objects → Inheritance and polymorphism → Encapsulation Build: Library management system 𝗠𝗢𝗡𝗧𝗛 𝟰: 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗖𝗼𝗻𝗰𝗲𝗽𝘁𝘀 → Error handling (try/except) → Generators and iterators → Decorators → Modules and packages Build: Custom data validator 𝗠𝗢𝗡𝗧𝗛 𝟱-𝟲: 𝗣𝗶𝗰𝗸 𝗬𝗼𝘂𝗿 𝗣𝗮𝘁𝗵 Web Dev? → Flask or Django → REST APIs, databases Data Science? → NumPy, Pandas, Matplotlib → Data cleaning, visualization Automation? → Selenium, script writing → Task automation AI/ML? → scikit-learn, TensorFlow → Basic models I stopped watching tutorials. I started building projects at every stage. Even bad projects teach more than perfect videos. The pattern that works: ❌ Learn everything → Try to build ✅ Learn basics → Build → Learn more → Build bigger Every new concept = one small project. No exceptions. If you are completely new to python, I would recommend w3schools.com to start with. Trust me, you will have a very good grasp over the language. Python isn't hard. Learning without direction is. Get a roadmap. Build as you learn. Watch progress compound. 📄 Here is a compiled a complete Python learning roadmap with project ideas for each stage... from variables to production-ready applications. Comment "PYTHON" and I'll send it over. 🔁 Repost if someone in your network is stuck in tutorial hell ➕ Follow Arijit Ghosh for more strategies to learn in the right way. #Python #Programming #LearnToCode #Coding #WebDevelopment #DataScience #MachineLearning #CareerGrowth

Python Refresher — Day 2: Data Types & Type Conversion 🐍📘 As part of my structured Python revision, I’m focusing not only on “writing code” but also on building strong fundamentals through deliberate practice 🧠✅ One exercise that challenged me today was: Predict the output (without running the code). Even in this AI era 🤖✨—where answers are instantly available—I intentionally chose to compute results mentally (no IDE, no shortcuts) to strengthen my understanding and logic, even though I went wrong in the answers in my first attempt💡📈 Here are two quick examples that reinforced an important concept: truthiness in Python ✅ 🧠 Code Snippet 1 print(bool(0), bool(1), bool(-1)) ✅ Correct Output: False True True 📌 Learning: 0 is falsy ❌ Any non-zero number (including negatives) is truthy ✅ 🧠 Code Snippet 2 print(bool(""), bool("0"), bool("False")) ✅ Correct Output: False True True 📌 Learning: An empty string "" is falsy ❌ Any non-empty string is truthy ✅ — even "0" or "False" (because they’re strings, not booleans) 🎯 Key takeaway for me: Truthiness in Python depends on emptiness / zero-value, not on how something “looks” or “reads” 👀➡️🧠 Continuing this journey with a Kaizen mindset — 1% improvement every day inspired from the book #Ikigai 🚀📌 “Progress often looks small at the beginning—but consistency makes it undeniable.” 📈✅ “Not everyone will value the basics—but results always speak.” 📊🔊 “Rome wasn’t built in a day—neither is mastery.” 🏛️🧠 #Python #Learning #Programming #SoftwareDevelopment #DataTypes #ProblemSolving #ContinuousImprovement #Kaizen #SelfLearning #LearningByDoing #Upskilling #PythonLearning #Competence #GrowthMindset #Discipline #DailyLearning Monal S.

You can tell a lot about a Python developer by how they use lists. Beginners see lists as a place to store values. Experienced developers see them as a tool to control flow, shape data, and simplify logic. append() is not just adding data. It’s building sequences step by step. pop() is not just removing elements. It’s controlling state. insert(), extend(), remove() small methods, but they quietly influence how clean or messy your code becomes. The interesting thing about Python is this: Many powerful programming habits start with very simple tools. Lists are usually the first data structure we learn. But they’re also one of the ones we keep using for years. Simple syntax. Serious power. Sometimes the most “basic” features in Python are the ones you never outgrow. #Python #DataScience #Ai #Lists

🐍 Python Sets — Store Unique Values Only 🔹 Sets are unordered collections that automatically remove duplicates. Perfect for when you only want unique items 👇 # Create sets directly number = {1, 2, 3, 4} # Create set from a list fruit = set(["apple", "banana", "orange"]) # Remove duplicates from a list score = [85, 23, 53, 85, 33] unique_score = set(score) print(unique_score) ✅ Output (order may vary): {33, 85, 53, 23} 💡 Beginner Explanation ✔️ number = {1,2,3,4} → Simple set with numbers ✔️ fruit = set([...]) → Convert a list to a set ✔️ unique_score = set(score) → Remove duplicate values from a list 🔑 Key Features of Sets • Only stores unique values • Unordered → cannot access by index • Useful for removing duplicates, membership checks, and set operations 🔥 Example Use Case: students = ["Ali", "Sara", "Ali", "Danial"] unique_students = set(students) print(unique_students) # Output: {'Ali', 'Sara', 'Danial'} 🚀 Sets make your Python code cleaner when working with unique data. #Python #Coding #Programming #LearnToCode #Developer
